IMPROVEMENT IN KITES.

Specification forming part of Letters Patent No. 117,270, dated July 25,1871 antedated July 18, 1871.

To all whom it may concern:

` will render it lighter than the surrounding air,

which assists it in rising and sustains it in the air, although theremay be little or no wind blowing at the time. The advantage of thisarrangement is that the iirst part of the operation in tlying the kiteis made less diiiicult, until it has risen a sufficient height to bemoved upward by the current of air.

The accompanying drawing represents my kite in a perspective View, andis constructed as follows: y

A is the body of the kite, which is made of any suitable material, suchas rubber, being made thin to give it lightness, and suiiieiently strongto resist the pressure ofthe gas within. At a a are left small pendants,to which the strings are attached, all of which converge to the pointcontinuing from thence in a single strand. av1 al are flexible necks,communicating between the interior ofthe kite and the free air without.A string f or ine strong thread is tied around the necks all al afterthe gas has been let within to keep the kite closed. The body of thekite is divided into two lobes by the junction of the top and bottomwalls, as seen at a? in the drawing. It may be necessary to connect thetwo walls by one or more additional connections, to prevent the kitefrom assuming too round a shape.

The operation of my invention becomes obvious. l When the kite has beenlledwith gas, and the neck al secured, as described, it will besuflieently light to rise in the air without the necessity of drawing itrapidly along, as inthe usual way. It is not intended to depend on thelightness of the kite to elevate it to any great height, or more thanwill be enough to bring it in contact with the currents of air above theground, at which place it will then be taken up further by the wind, asother kites.

The amusement thus offered to the young will be greatly increased bythegreater ease of starting the kite, and also its tendency to i'lylighter, owing to its lightness compared with the surrounding air.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A kite, constructed of two parallel walls connected by a strip of thesame material and properly stayed to keep the kite-shape, `the spacebetween the walls to be iilled with gas lighter than common air,substantially as described.
